Let G be the family of all c-connected (c = 4 or 5) polyhedral supergraphs G of a given connected planar graph H where the minimum vertex degree of G is 5. Let R(H) denote the maximum face size of H. We have proved for all non-empty families G: In the case R(H) , every G ∈ G has a subgraph isomorphic to H whose vertices have a degree in G which is restricted by a number q = q(H,G). In the case R(H) ≥ c, such a restriction does not exist if H has a vertex of degree ≥ 5 or if H is 3-connected.
